The Best Web Services Article I have Read in a long time

Don Smith has recently published the best article
I have read on Web services security. It is not light reading, but he does
an incredible job putting very difficult to understand topics in very consumable bites
with lots of why, what, and how. It shows you how to get real work done
using Web Services Enhancements for Microsoft .NET.

How many of you out there need to establish trust relationships with business
partners (internal and external)?

How many of you out there use heavy cryptographic keys when
bootstraping a secure communication between Web services and need a lighter weight
symmetric key for secure conversations?

Let me know what you think about this article
and if you plan to implement WSE to solve your security problems.
